To format the electron configuration correctly make sure to superscript where needed, do not add spaces to your answer and italics are not possible in this module. Write the ground-state electron configuration for calcium, Ca. You may write either the full or condensed electron configuration.

 [full configuration]

Explanation:

Calcium has 20 electrons in its nucleus, and by virtue of its position on the periodic table (fourth row, second column), it is an s-block element with its entire lower orbital filled. it has two valence electrons.

Therefore, its configuration is:

To condense this, you can utilize Argon's stable configuration before to show that all orbitals before 4s are filled.

I hope this was helpful.

im not exactly sure but i think its b!

i don't know people like to fight everywhere rip.
